The square cube law does indeed state that larger objects that are identically proportionally constructed of the same materials will actually be more massive...

That is, of course, the central theme of my post. We don't find skeletons. we find fossils, and in the case of mega-dinos, we find a few bits and pieces.

Much of the compensation for the weight problem would be found in the internal structure of bones. Are they bird-like?

Again, you assume that because bio-physics is not a mature science, the uncertainties require overturning Newton and Einstein. I say bullshit.

A Teratorn WAS a bird... and we have entire skeletons.

What makes you think that Bio-physics is not a mature science? And who is overturning Newton and Einstein... not me. There are potential answers to this dilemma that do not offend either Newton or Einstein (ignoring for the moment that Einstein's work in some instances invalidated Newton). The point is to not ignore the data, sweeping it under the rug.
